The "red light" position of some resistance and sede clergy towards the SSPX only does spiritual harm for Catholics deprived of the sacraments. One can only wonder how many Catholics have needlessly avoided decent SSPX chapels that are their only option for sacraments because of this ignorant viewpoint.
Ignorant? The complete opposite is the case. It sounds rather intellectually snobby of you to put things that way.
I am growing weary of hearing how it can do harm to avoid modernism and it's sacraments.
The sacraments are not emotional cushions. They are there to give us grace. If you choose to have emotional comfort knowing full well that this runs the very real risk of exposure to modernism, by omission as well as active word and deed, then I cannot see how you are not committing a sin.
There is risk in everything, but considering that the SSPX is now part of the Conciliar Church, it is too much of a risk.
Additionally, if you go to SSPX, then why stop at that?? Go to indult also. Why not go to the Latin, ad orientem Novus Ordos? I mean if it is only about liturgy, many of them are also good.
But if it is about the faith, then why can't you be consistent? Drawing a line to the left of the SSPX makes no sense from a rational point of view. You make it all subjective at that point, when there are very real objective markers which can be used. Bishop Tissier de Mallerais, back when he was Catholic, used the example of St. Hermenigild, who refused to receive the sacraments from an Arian Bishop, even though they had perfectly valid Masses. Validity is not enough. We are forbidden by Canon law to attend Eastern Orthodox sacraments, even though they are valid, because their position is against the faith. The same is with modernism. Modernism is outside the Church. It is not Catholic. This really is very simple.
